A further object of the invention is the profor a vision of a devicefor removing dirt from the foot roller of an elevatlng grader 1n order to maintain the belt trained on said roller in its proper position, the dirt being discharged into a dust pan and removed by an automatically driven plunger held in guides in the dust pan.

lVith the preceding and other objects and advantages in mind, the inventionconsists in the novel combination of elements, constructions and arrangements of parts and operations to be hereinafter more fully described, claimed and illustrated in the accom- V panying drawings, wherein: Figure 1 is a plan view of an elevating grader with parts broken away disclosing my invention applied thereto; i i

F'g. 2 is an enlarged transverse vertical section taken along the line 22 of Fig. 1; Fig. 3 is a fragmentary end view partly in section showing the traveling conveyor;

Fig. 4 is a view in perspective of a foot roller in operative. relation with a dust pan and cleaner; and V a Fig. 5 is a fragmentary side view showing my invention applied to the grader.

Referring more particularly to the drawings 1O designates the frame work of an elevating grader supported from a longitudinal bar 11 of circular cross section and this bar is supported by a depending member 12 connected with the front axle 13. Amember 14 depending from the rear end of the bar 7 wheels 17. The axle is rigidly secured to the wheels 17 so that said axle is thereby Irevolved. t

A spur gear 2-0 is secured to the axle 16 jacent the travelling carrier and these trier.

11 in connection with brace bars 15 is sup ported by an axle 16 upon which are mounted and meshes with a gear 21 mounted loosely on a shaft 22 carried by a bearing 23 dependingfrom the member 14.- A rod-24' is connected with an eccentric pin 25 carried the gear 21. It :will beinoted that the gear 21-has' a plurality of passages'26vinradial alinement which 'areadapte'd-to receive the eccentric pin 25 for increasing or decreasing the length of the path of "movement of the i rod'24'as will be presently explained. A travellingcarrier 30 is trained over a foot-roller 31 which is formed of steel and has'trunnio-ns 32 supported in bearings 33 atthelower'end of the tractor. The 'trunnions are carried by V plates 34 which have their upper edges'adplates act as a support for the travelling car- The belt 30 is driven in manner, not-shown, v a

A- dust pan 35 in the form of a channel ex: tends transversely between the sections of the travelling carrier 30 and adjacent the foot roller 31; This-dust pan is provided with a base ,member 36 and an inclined scraper blade 37 forming one side wall of the dust :pan adjacent the roller 31. This blade has an any approved edgewhich is in engagement with the roller section and has an inclinedface 43 forming a longitudinal'side ofthe dustpan 35 is spaced from the floor 46 by meansofa spacing bar,

44. The spacing bar 44 and wall 42 iai'e secured to the floor of the du'stpan to provide 7 a track 45 atone edge of the spacing bar 44.

i A cleaner generally designated by the numeral v46 is U-shaped in cross section and has a; lateral flange 47 received within the track 41.. The cleaner likewise has a lateralflange 48 received within the track 45 so that the cleaner may be moved longitudinally of'the 1 dust pan and maintained in position byithe r flanges 47 and 48 and the fl'ange49 of: the scrapingbl'ade 37 and the bottom of the. wall 31 at points between the sectionsof the'trav- Y 42. The opposite ends of the cleaner are closed in order to engage the dirt for forcing the dirt through the openings and 51 formed in the plates 3% The link or rod 24-. is connected at 52 to a U-shaped member 53 which is secured at 54 to the cleaner 46. A shovel carried by an arm 61 which is secured to thegrader in any approved manner is locatedeat such an angle relativefltoithe the "pan being connected to the base member and having a portion spaced from said base member to provide a second guide element, a scraper element having laterally disposed flanges received by the guide elements and slidablymounted in the pan.

roller 31 that it will engage the dirt and force i the same upwardly and upon the travelling carrier 30 and the travelling carrier carries the dirt and deposits 'it in a well known' manner.

The operation of my device is vas follows: As the elevating grader'is carried" along the i, pieceof work the plow orshovel 6O forces the dirt upon the lower end ofJ-the travelling car; 7 I

rier 30 and this dirt is carried along by the moving carrierto an elevated point. 3 During the operation of the grader dirt finds itsway between'the sections of the belt 30 andficomes in contact with the roller 31. and ifthis dirt were not-removed it would cause uneven 5 places on the-foot roller so that the travelling carrier belt would be thrown out of alinement at timesandtend'to stretch the belt unnecessarily. i

I The blade 37 which arms-bass wall 7; of the dust pan 3.5 has anedge38in contact with the roller at alltimes sothat-any dirt tending to collect upon this roller is scraped off and deposited within the dust pan.

Since the member 46 is reciprocated through the gears 20 and 21 and the link- 24 it-will be moved at all times during the operation of'the grader longitudinally of the dust'pan and thus continuously removing a dirt which has-been scraped from the foot operated by a lever pivotally mountedon the frame and connected with the rod 24'for causingmanual reciprocation of the cleaner.
